"...the emergence of exotic marathons, from Antarctica to the Sahara desert, reflects a restless energy and a desire on the part of many runners to keep pushing boundaries further and further. But it's also simply an interesting way to see interesting places."
The Coolest Race on Earth: Mud, Madmen, Glaciers, and Grannies at the Antarctica Marathon by John Hanc tells the story of this crazy marathon, the guy who started it, and the people who come to race it. Hanc also gives you a bit of marathon history and Antarctica exploration trivia. I've never wanted to run a marathon myself, but I admire those who commit to, and complete, such an arduous task. And the runners who travel to the farthest end of the earth to run 26.2 miles? Well, they are their own interesting breed. This book was an entertaining read that almost made me want to go to Antarctica, too. Here's a snippet from the author about why he chose to run the "Last Marathon":
It was time to get out of this funk and into a new frame of mind. A trip to Antarctica is a great remedy for this, provided you're not planning to spend the dark winter there, which, as numerous studies and several gory murders on remote scientific stations have proven, can drive you insane. Many compare the whiteness of the place to the blank page on a new chapter in one's life.
